Place 1 tablespoon of the sugar, warm milk, and yeast in a standing mixer bowl, whisk it, and let sit for 5 to 7 minutes or until it begins to foam. There will be a raft at the top.
Wrap the bowl with plastic wrap and set it in a warm place until it has doubled in size. If you plan on making the next day, chill in the refrigerator overnight.
Roll out the dough on a clean surface lightly dusted with flour until the dough is roughly 18”x 24” inches in size. Evenly drizzle on 1 stick of melted butter, brown sugar, and cinnamon.
